DarwinFPV 18650 Review | Fully 3D printed #NanoLongRange
The one i put on thingiverse, but it has a few lets – say modifications that are quite interesting. So what im going to do in this video today is take a closer look at um this frame and how this thing is set up overall and compared to what you can basically um the diy build at home with the thing reverse pages and the reckon free That you can buy in most shops like banggood or the reckon fpv online store. So if youre familiar with the original nano long range, one that is on thingiverse youll notice, that this is very similar in the overall geometry and some parts are obviously the same. So the bottom part part here is not really modified. The front part is the same, and this means they sort of remix the design which uh in principle they wouldnt be allowed to do uh for a commercial product, but uh, you know after after they got a few youtube comments, hinting them towards the fact that this Is violating some copyright laws they actually proposed um to pay, give me a share of the profits uh for this product. So i think this is fine. This makes basically makes this a legit remix um. That is not not stolen, basically from thing reverse all right, uh. So with that, out of the way lets look at this frame a little bit closer, because while this is a remix, it has a few substantial changes or say maybe two main changes.
The first one is that the battery tray this compartment here is fully integrated in the print, so the reckon free and the original thingyverse thing you needed this 3d um. This injection molded part here that is screwed on top of the frame where the battery goes in. This here has this basically integrated with the arms and the front part. Now the advantage is that this looks very elegant and its a bit lighter the downside. Obviously, if you break an arm on this quad here, youll have to replace the entire thing and completely rebuild it. So thats a bit of a disadvantage, but i would say, if youre really into 3d printing and you want a fully 3d printed quad. This is actually something that is is quite nice if youre a bit. You know a bit geeking out on 3d printed stuff, because this is not also its not only a regular 3d print, its a multijet fusion print. So this is nylon. This is stronger than what you will usually print at home and it does also have a surface treatment. So usually these nylon prints are really rough. This one, as you can see, has a nice shiny surface. So there is a sort of additional abrasive treatment where the surface here is made to be nicer, so in terms of 3d, printing and technology. This is a very interesting product because it is uh. I think its really the only fully 3d printed drone that you can buy on the market commercially uh.
Obviously, all fpv drones are almost all fpv. Drones have 3d printed parts, but this thing really is exclusively 3d printed, so i think that makes it kind of cool. I have to admit its not from my functionality and practicality. Standpoint: um, it doesnt make too much sense. The reckon free. Actually you know it makes more sense. The plastic parts are injection molded on the newer versions. Also, this bottom part in the front parts is all injection molded, so its more robust and it has carbon arms. So you can replace the arms its its more practical, especially if you crash from time to time, but this year, from the point of view of you know, technology, feasibility and engineering is a very, very cool thing, because its pretty much the only commercially available 3d printed. Drone now, apart from this super interesting frame, id say this is basic. Nano long range stuff, so we have a small cadets and obviously this is all analog. Then we do have some 1103 motors. So i think these are. These are pretty much the same volume as the 1202. that are on the right can free 12 000 kv is also quite close in kv. So i would say this is a regular one. As drive train lets, take a closer look at the electronics and uh quick disclaimer. Here i broke off the usb on uh on this quad when i first plugged it in so i had to swap out the flight controller, so this build is not as clean as it comes out of the factory.
This is my own soldering and so on. So its not super clean, but this is how it looks inside its quite nice that i stacked the vtx on top of the fc. Its all quite compact, in here small capacitor doesnt, seem to need a step up voltage regulator. It seems to work fine like this and uh. This part is actually quite interesting, its an f4 but its a one to three s: 15 amp esc. I think this is the in terms of amp rating. This is the strongest one esport that im aware of so quite interesting, um yeah but basic stuff in here. Nothing, nothing too crazy, but also i mean this all looks quite solid and will probably work fine and its quite nicely built and again in the original, even cleaner than i built it here, alright, so with the bottom screwed back on lets. Take this thing outside and see how it performs uh im not expecting something very surprising, its probably going to perform quite close to the record, free and other nano long range builds, but lets take it outside and lets try this thing out all right. So unfortunately, i just realized that the file on my sd card got corrupted. So i cannot edit the edit in the dvr, but let me tell you that this thing actually flies very nicely. Darwin git did a really solid job on the tune, and i would say this is at least on par with the reckon free.
So i think you will be getting some very nice flight performance here. Out of this nether long range and the 3d printed frame doesnt seem to impact this at all flies, really, nice, all right, so whats your whole conclusion and i would say, um to do this conclusion. First of all, we need to discuss a bit what this whole long range concept is about, because the nano long range concept has never been fully about being your everyday quality fly all the time, and that flies absolutely amazing. They all fly okay, but you know its not great its, how what you would expect from something that is powered by a single cell or only three volts, its not super impressive. This entire thing, always in this entire hype, always was about technology and feasibility in early adoption, to try something new and to prove that its possible to fly on a single cell, which is something really cool and kind of satisfying. If you just pop in these batteries and your quad is working, so i think in this way this is really in the spirit of that, because its fully 3d printed theres, no injection molded part theres, not a piece of carbon on there. So this kind of even takes the concept further its a commercially available, fully 3d printed quadcopter that is powered by just a single 18650 cell. Now the downside of that is obviously its its even less practical than the reckon 3, because the reckon 3 is at least repairable.
You have carbon arms, you have injection molded parts in the front. Taking the impact so nurikenfree is, will take more crashes and is obviously more durable than something that is fully 3d printed and when it breaks you have to replace this. I dont i dont even know if they sell a spare frame. I think so, but youll have to replace the entire frame, all the motors everything, so you need to completely rebuild it. So its not going to be very practical, but then again, i think its more of a proof of concept. Technology thing that is very nice if youre into these things, this might be something you just want to try and want to have and enjoy sometimes um. Another advantage of the 3d printing here is that this thing is very cheap. Its a bit, i think its. Like 30 dollars cheaper than a reckon free, because i mean obviously this is very easy to manufacture. The reckon free has injection molded parts which are expensive to make, because you need small need molds, it has carbon parts, it needs to be cut. The whole thing needs to be assembled with these nylon prints here. Basically, what you do is you have a big industrial printer and you let that thing run all night and in the morning your prints pop out you clean them up, you do the surface finishing and youre basically done. This is very cheap to make so thats another advantage of the 3d printing here um i mean.
Finally, in the end, i think its up to you to to pick which one is the most interesting for you and what you enjoy. You might even like to um. You might prefer building your own entirely and again. The files for the 3d printing are in thingiverse, so feel free to get them put your own frame and do your own diy builds.
